45853356 divided by 321 
Our goal is to divide 45853356 by 321.

Advancing to step 1:
If we divide 4 by 321, we get 0 and a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 321

On to step 2:
321 goes into 45 0 times with a remainder of 45.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 45, we get 45.
Fetch the next digit (8) from the dividend, attach it to 45 and continue: 458 / 321

Going ahead to step 3:
321 can be fit into 458 1 times, resulting in a remainder of 137.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 321 from 458 and we're left with 137.
Fetch the next digit (5) from the dividend, attach it to 137 and continue: 1375 / 321

On to step 4:
The number 321 fits into 1375 4 times, leaving a remainder of 91.
Use 4 as the next digit of our solution. 
Result so far: 14.0
Subtracting 1284 from 1375 leaves us with 91.
Include the next digit (3) from the dividend after 91, then repeat: 913 / 321

Let's proceed to step 5:
If we divide 913 by 321, we get 2 and a remainder of 271.
Put 2 as the next digit of the answer. 
Result so far: 142.0
Deduct 642 from 913 and we're left with 271.
Take the next digit (3) from the dividend and append it to 271, then repeat: 2713 / 321

On to step 6:
321 goes into 2713 8 times with a remainder of 145.
The next digit of our result is 8. 
Result so far: 1428.0
Subtracting 2568 from 2713 leaves us with 145.
Bring next digit (5) of the dividend behind the 145 and repeat the process: 1455 / 321

On to step 7:
1455 divided by 321 is 4 with a remainder of 171.
Put 4 as the next digit of the answer. 
Result so far: 14284.0
Subtract 1284 from 1455 to get 171.
Bring next digit (6) of the dividend behind the 171 and repeat the process: 1716 / 321

Step 8:
The number 321 fits into 1716 5 times, leaving a remainder of 111.
Write down 5 as next digit of the result. 
Result so far: 142845.0
Subtract 1605 from 1716 to get 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

Going ahead to step 9:
The number 321 fits into 1110 3 times, leaving a remainder of 147.
Write down 3 as next digit of the result. 
Result so far: 142845.3
The remainder is 147 after subtracting 963 from 1110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

Step 10:
The number 321 fits into 1470 4 times, leaving a remainder of 186.
The next digit of our result is 4. 
Result so far: 142845.34
If we take 1284 away from 1470, we end up with 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Moving on to step 11:
321 goes into 1860 5 times with a remainder of 255.
Write down 5 as next digit of the result. 
Result so far: 142845.345
Subtracting 1605 from 1860 leaves us with 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Advancing to step 12:
2550 divided by 321 is 7 with a remainder of 303.
Write down 7 as next digit of the result. 
Result so far: 142845.3457
If we take 2247 away from 2550, we end up with 303.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3030, and continue the process.

On to step 13:
321 can be fit into 3030 9 times, resulting in a remainder of 141.
Record the quotient 9 as the next digit in the result. 
Result so far: 142845.34579
Deduct 2889 from 3030 and we're left with 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

Let's proceed to step 14:
1410 divided by 321 is 4 with a remainder of 126.
The number 4 becomes the next digit in our result. 
Result so far: 142845.345794
The remainder is 126 after subtracting 1284 from 1410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

On to step 15:
1260 divided by 321 is 3 with a remainder of 297.
Use 3 as the next digit of our solution. 
Result so far: 142845.3457943
If we subtract 963 from 1260, we get 297.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2970, and continue the process.

On to step 16:
If we divide 2970 by 321, we get 9 and a remainder of 81.
The next digit of our result is 9. 
Result so far: 142845.34579439
If we subtract 2889 from 2970, we get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Our division results in 142845.34579439 with a remaining 8.1e-08.
